Letters Patent No. 110,783, dated January 3, 1871.

IMPROVEMENT IN FASTENlNC-iS` FOR B'RACES, dac.-

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern Be it known that I, EDWARD LAWLEY PARKER, trading under the firm of Bent &; Parker, of Birmingham, inthe county of Warwick, England, manufacturer, asubject of the Queen of Great'Britain, have invented or discovered new and useful Improvenients in Fastenings for Braces, Belts, Bands, and other articles and I, the saidEDWARD LAW- LEY PARKER, do hereby declare the nature of the said invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof, that is to say:

My invention consists ofthe improvements, hereinafter described, in fastenings for braces, belts, bands, and other articles.v I

I will describe my invention as applied to a fastening for braces.

When applied to a brace-fastening my'said invention is employed to connect the tab-plate of the fastening to the body or frame of the fastening.'

0n the lower part of the said body or frame is a projecting piece, having two symmetrical perforations orppenings made in it, and between the saidfperforations is a bar. This` b ar is narrow at its upper part, enlarges to a nearly circular figure at the middle, and contracts at its lowerfpart.

0n the upper part of the tabplate are two springhooks.

By introducing these hooks into 'the perforations or openings in the frame, they4 pass the upper narrow part of the bar and clip orembrace the enlarged middle part of the bar.

By pulling downward the tabplate, the springhooks open and pass the enlarged part of the'bar andv close by their elasticity upon the lowerA contracted part of the bar. To release the tab-plate it is pressed upward. The spring hooks are thereby made to open and escape from theenlarged part ofthe bar.4

In applying .the invention to belt or band-fastenings, Vthe acting parts remain the same, bntthe two endsv of the belt or band are connected to loops or frames on the said acting parts. i

I will now proceed to describe with reference to the accompanying drawing the manner in which my invention is performed.

Figure l represents in front elevation, and

Figure '2, in side elevation, a fastening for braces.

containing my improvements. p

Figure 3 represents the body or'frame-of the same separately, and

Figure 4 represents the tab-plate separately. a is the bodyv or frame of the fastening, on/ the lower part of which and in one piece therewith is `a projecting plate, b, in the same plane as the said body or frame,

vIn ,this plate b are two symmetrical perforations, c c, which, together, form an opening of an oblong iigure witha bar, d, at its middle.

The bar d is narrow at its upper part, and enlarges t'o a nearly circular -ligure at its middle, and contracts at its lower part,.the said lower part, however, being mchbroader than the upper part.

c is the tab-plate, to be connected to the body or frame a of the fastening.

On the upper edge offthe tab-plate e are two spring arms, ff, the upper ends of which are curved out of the plane of the tab-plate,`and folded or doubled so asto form two hooks, f 2 f2, the open inner sides of which are presented to each other, (see the plan View, v. 4.)

z:The ends of the hooks f 2 f2 are situated at such a distance apart that when they are introduced into the perforations or openings c vc of the plate b, they readily pass the upper narrow part of the bar d, and clip or embrace the enlarged or circular middle part ofthe said bar. When in this position, by pulling or pressing downward the tab-plate e, the spring-hooks f2 f 2 l of the spring-arms f f open and pass the curved or' enlarged part of the bar d, and close by their elasti ity upon the lower contractedpart of the said bar d, as seen in iig. 1. ,The connectionof the tab-plate cwith the frame or body of the brace-fastening is thereby complete. l

In order to detach .the tab-plate e from the frame it is necessary to press the said tab-plate e upward with suicient force to canse the spring-hooks f 2 f 2 to expand or open and pass the curved .or enlarged part of the bar d, after escaping from which the tab-plate is detached from the frame a.

Inapplying my improvements to fastenings for belts, bands or other articles, I combine the connecting partsb c d and c ff2 with frames or loops, and secure one end of the belt or band to the loop of the eye part, and the other end of the belt or band to the loop of the hook part.

By engaging the hook part with the eye part in the manner described with respect to abracefastening,

the two ends of the-belt or band are connected together. p A .I prefer to make the parts of the fastenings from sheet metal by the process of stamping, but they may be -inade in other ways..

.Having now described the nature of my invention and the manner in which the same is to be performed,

I wish it to be understood that I do not limit myself to the precise details. herein described'and illustrated, as the same may be varied without departing from the nature'of my invention; but

I clairii as my invention- Y The improvements hereinbefore described and i1- lustrated in the accompanying drawing, in connecting together and' disconnecting from one another, the two parte of fastenings for braces, belts, and other articles; that is .to say, the ,perforated plate b e d of the one part of the fastening, and the spring-arms and hooks ff2 of the other part of the fastening, said part-s being arranged for joint operation, substantially as described and illustrated.
